ATTACHMENT FOR OREELS.

Application filed March 26, 1923. Serial No. 627,755.

To all whom it may concern:

Be it known that I, ARTHUR L. REMING- TON, a citizen of the UnitedStates, residing at lVorcester, in the county of Worcester andCommonwealth of Massachusetts, have invented a new and usefulImprovement in an Attachment for Creels, of which the following,together with the accompanying drawings, is as specification.

My invention relates to creels or spool stands, such as are employed forsupporting a plurality of spools so that the yarn may be convenient-1yled therefrom to a winding machine of any desired type, or directly to aloom.

The object of my invention is to provide an improved attachment for acreel or spool stand, whereby the amount of friction to which theindividual warp threads or strands of yarn are subjected to, as theyleave the creel, can be readily controlled in accordance with the natureof' the yarn and the manner in which it is to be handled after leavingthe creel. By my invention it is possible to substantially eliminate thefriction to which the yarn is subjected, or to so regulate it that eachthread is subjected to the same amount of friction. The above and otheradvantageous features of my invention will hereinafter more fullyappear, reference being had to the accompanying drawings in which Figure1 is a View in side elevation of a portion of a creel'showing myinvention applied thereto so as to eliminate friction on the yarn.

Figure 2 is an enlarged, perspective view of one of the cross bars ofFig. 1.

Figure 3 is a view in side elevation of a.

portion of a creel with my invention applied thereto so as to providefor a uniform amount of tension on the yarn.

Figure 4 is an enlarged perspective view of one of the cross bars ofFig. 3.

Figure is an enlarged detailview of o a roll support embodying myinvention.

Figure 6 is a sectional view along the line 66 of Fig. 5.

Like reference characters refer to like parts in the different figures.

Referring to Fig. 1, a portion of a creel is shown, which consists of anumber of spindles 1 arranged in rows, each of which carriesa spool orpackage 2 of yarn. An

upright 3 is provided at the front of the creel, upon which is mounted aplurality of cross bars 4, each extending across the front of the creel,the number of cross'bars 4 corresponding to the number of rows of spoolsor packages 2. As best shown in vFig. 2, each cross bar 4 is providedwith-a plurality of eyes 5 corresponding in number to the number ofspools or packages 2Ain a given row, and each eye 5 is'provided with acentral opening 6 for the passage of the yarn therethrough.

With creels as previously constructed, it has been customary to lead theseparate strands of yarn directly from the eyes 5 to a suitable windingmachine, or loom, which provides a roll 7 on a support 8 over thesurface of which all of the strands pass. As the roll 7 is locatedbetween the lowermost and uppermost cross bars 4, it is apparent thatthe several layers of threads will make difi'erent angles with thehorizontal as they converge upon the roll 7. Consequently the layer ofthreads passing through the eyes 5 in one cross bar 4 will be subjectedto a certain amount of friction as each bends over the lip 6 of theopening 6, and it'is apparent that the amount'of friction will Vary withthe different angles which the Various layers of threads make with thehorizontal. hen handling very fine yarn possessing but little tensilestrength, it has been found that the variations in the amount offriction to which the different layers of threads are subjected, giverise to very undesirable results when the yarn is Wound, for the reasonthat difierent layers of yarn have been stretched unequally. Y It is theobject of the present invention to provide an attachment for creels,whereby the above described unequal stretching is avoided by thesubstantial elimination of friction at the point where tllQtllIQitClSleave the creel.

rolls 9, each extending across the creel in front of a cross bar 4. Asbest shown in Fig. 2, each roll'9 is so supported with respect to acrossbar 4 that a thread passing through the opening 6 of any one of the eyes5 will engage the periphery of the roll 9 without touching the sides ofthe opening 6. In other words, each roll 9' is so support- To this end Ihave provided a plurality of l ed with respect to thecorresponding-cross bar 4. thatthe' 'threads passing through the eyes 5of a crossbar are'all tangent to the surface of a roll 9, from whichthe'threads pass to the roll 7 of the Windinganachine' respective axesof rotation below the-"c one" sponding series of eyes 5, while the rolls9 below the top of the roll? are mounted with their respective axes ofvrotation above the corresponding-eyes- 5, the above statementholdingftrue' regardless of 5 the locationof the 011-7 with respect-tothecross bars 4.

With the improved arrangement shownin Fig'rl," it is apparent that eachindividual threa'c'l passes throughthe opening-'6 i of 1 its eye fiwithouttouching=theeye, so that frieti o'nal engagement between thethreads and the eyes *is *eliminated; As the threads pass over'or underthe seve'ral rollers 9 at difi'erent'angles from the horizontal,whatever frictional engagement there may be between the' yar'n" and theroll's*9 is substantiallythe same for each individual; thread; because"of the factthatthe rolls 9 are free to turn on their respective"aic'es. From the foregoing then 'it follo ws that very fine yarn may betaken I frein the creel with the arrangement showman Fig. 1, Withoutsubjecting the individual threads to difi"erent' degress of tension. 7

' When hand'lingcertain kinds of heavy yarn or cold, it issometimesdesir-able that *the threads be subjectedto' a certain'ainountof tension" as they pass from the creel, a specific instance being "in"the" manufacture of fabrieifor cord tires." In the" production ofcord-fabric it has been proposed to-we'ave therelativelystron'g'andfh'eavy cords which com'prises" the warp, directlyfrom the spoolsor packages of a" creel, so that the necessity forbeaniin'g the warp is eliminated; When" warpthreads are taken directly'from a creel to a lo'on'r it is desirable thatthe threads be'su bj'ectedto a certain amou t of tension, although in i this case it is" veryessential that the tension in" each thread be? the same; Thepresentinvention also contemplates a modification erthearrangement shown- F ig:1, whereby the threads taken from the creel=- are 'eac1r subjected" toan equal amount of 'tension, which may" be regulatedlteferring nowtoFig. 3, there is shown a portion of a' creel comprlsing the usual'spindlesliO,'spools or packages' 11', and cross bars 12 ealieh having arow of eye's13i As best'shown in Fig. 4,41 roll 14 is'rotatablysupported in front-of, and below each'cross bar 12', so that a threadpassingthrough the opening-150i an eye 13 to the-roll 14- willbedrawn'over the lip1'5 at a-definite. angle,

' which" is" the same for-eachofthe rolls 14.

' After passing-under the rolls- 14* the threads passftoa rolll6 on astand 17 which'may be placed in front of a'loom, to "which the threadspass directly for forming the warp of a fabric; It is apparent froman-inspectionof- Fig: 8, that- -each thread will be subjected to acertainnmou-nt of friction as it is drawn downwardly over the lip 15 andthatithis friction will be the same for each individual thread.Consequently all of the threads-will pass to' the loom with a certainamount of tension which will be uniform. The fact that theseveral-layersof threads converge upon the roll '16' at'ditferen'tangles to the horizontal, does not :m'ateria-lly affect thedegree of tension in' the threads because of the fact that each of therollslt isfree to rotate on its 'axis,"ther'eby substantiallyeliminatingfriction between the threadsand the rolls 14.-

Referring now'to Figs, -5 and 6,";ther'e is shown a cross bar 18 havinga fixture 19 attached theretd for rotatably"supporting one end of aroll20' insuch a -mann'er that it may be employed in connection withxeitherof the arrangements shown in" Figs. lrand '3. The fixture 19 provides anannular portion 21 within which is received a 'di'sk122 tu'rnabletherein, and" ad'apted' to" be' 'se'curedin any desired angularposition-by aset screw 23. A pin 24 is carried? by the disltf221eece'ntrio to the axis of'the" annular portion 921,-

and theroll 20 is rotatably' supported at one end by'the pin- 24 Afixture'ssimilar'to the-fixture 19 is provided at theioth'er end of thecrossibar 18 forsuppnrtingthe other end of the roll 20. I1r=the full:line position,- the roll 20 is sov supportedthat a-rthread passing"through the opening; 25 0f an eye 26-is tangent to its periphery.Byturning the" disk 22, the roll 20; maybe brought into the dottedlinepositionsothat a thread pass- 1 ing through the openingz25' is drawndownwardly over the lip 2 5 inwpassing to the roll 20.

my invention I 'haVe provided an improved attachment for use inconnection witlrcree'ls or spool stands, whereby the: amount. offrictionto which the threads aresubjected in passingthrough. the cross bars ofthe" creel is: always maintained substantially iinidferm 1 and may bevaried from'substantially: zero to a definite amount, asmaybe desired.-
